Dr. Peter Burke, chief of trauma services at Boston Medical Center, told reporters on Wednesday that the two patients remain in critical condition at the hospital, including a five-year-old boy.

Burke said the hospital received around 10 or 11 critical patients after the marathon blasts. In addition to the two critical patients, 10 are in serious condition and seven are in fair condition, Burke said. The patients' ages range from 5 to 78, Burke said.

"Most patients are making good progress through the process," Burke said.
